Specification of Letters Patent.

Application filed June 9, 1909. Serial No. 501,004.

T 0 all whom "it may concern:

Be it known that I, CARL ALGOT JANSSON, a citizen of Sweden, and aresident of J ersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inTobacco-Pipes, of which the following is a specification.

This invention relates to improvements in or appertaining to pipes forsmoking tobacco, the general object of which is to afford the user acool and sweet smoke free from the venomous alkaloid commonly termedtobacco oil The specific object of the invention has been to devise atobacco-pipe including none but the ordinary parts outwardly, and which,though simplest in construction, may be most effective for the purposein View. Pursuant to this idea, the present invention does not divide upnor increase the length of the pipe-stem, nor does it consist of anattachment to the exterior thereof, but is found instead in the internalstructure of the stem and a certain smoke-deflector therein contained,as will now be described in de tail, with reference to the accompanyingdrawing.

In the said drawing,-Figure 1 is a sec tional elevation of atobacco-pipe made ac cording to the said invention. Fig. 2 is across-section on the line 22 of Fig. 1. Fig. 3 is an enlarged side viewof a modified form of the deflector above referred to as contained inthe pipe-stem. F igsp l and 5 are, respectively, a left-hand end viewand a right-hand end view of Fig. 3. Fig. 6 illustrates anothermodification of the deflector in enlarged side view, and Figs. 7 and 8,respectively, show left and right end views of Fig. 6.

The pipe proper is composed of the usual parts, comprising a bowldesignated by the reference numeral 11 herein, a stem 12 integraltherewith, and a mouthpiece 13 fitted in the outer end of the said stem.Interiorly, the stem 12 is recessed at 14, in the said outer endthereof, the recessed portion 14 being larger than the bore 15 of thestem, which it partly replaces and with which it communicates. Themouthpiece 13 is eX- teriorly rabbeted at 16, which forms a re ducedbody portion that enables it to close the peripheral part of the recess14. A bore 17 of the mouthpiece 13 is brought into axial register withboth the said recess and the bore 15 thereby affording a continuouspassage for the smoke from the bowl 11 to the suction end of the saidmouthpiece 13. As shown in Fig. l the marginal configuration 18 of themouthpiece, at the base of the reduced portion 16, may be made to bearagainst a flanged ring 19, encircling the adjacent end of the stem 12.

Within the recess 14 lies the aforesaid smoke-deflector. The three formsof this device which the annexed drawing shows are alike in theirfunctional characteristics and practically the same also in generalconstruction, although varying in structural detail. As regards theirsimilarities, all three forms consist each of a two-part deflector,comprising two outwardly-flaring, oppositely-turned, non-communicatingcompartments that are lobate in cross section and more or less parabolicin axial section; and all said forms are capable of being lodged in therecess 14 after the manner exemplified in Fig. 1, wherein the deflectoris represented as extending from end to end of said recess, with oneflaring part directed toward the bore 15 of the stem 12, and with theother flaring part inclosing a neck 20 of the mouthpiece 13, throughwhich the bore 17 runs. The several forms are made preferably ofnon-absorbent material, such as glass or metal. As to the differences ofstructure between the three forms, they will be noted in rotation, eachform being considered in its regular order.

Referring first to the construction illustrated in Figs. 1 and 2, theform of de flec'tor therein shown is made from a trilobed tube, twistedin the middle to divide it into two separate compartments 21 and 22,opening outwardly from the ends in opposite directions, and havingreversely inclined surface grooves 23, with acentral annular depression24 intervening therebetween.

Figs. 3, 4 and 5 illustrate a smoke-deflector differing from the onejust described only in that the sides of the tube of which it is formedare fluted as well as lobated, hav ing corrugations 25, that alternatewith the lobes and are separated therefrom by surface grooves 26,oppositely inclined from the central twist, which is circumscribed bythe depression 27. This depression constitutes the dividing zone betweenthe two compartments 28 and 29 of the modified smokedeflector, whosedistinguishing feature resides in said corrugations, the same being anaddition to the previously described structure.

The deflector represented by Figs. 6, 7 and 8 is merely crimpedcentrally at 30, instead of being twisted. Its two ends, therefore, arealike. Otherwise it resembles the other two forms of deflector bothbefore described, having tri-lobed compartments 31 and 32, withreversely-inclined grooves 33 in their respective surfaces and anintermediate depression 3%.

YVhichever form of the deflector is used, it is placed on its sidewithin the recess 1% of the pipe-stem 12, prior to the insertion therein of the reduced portion 16 of the mouthpiece 13, or after withdrawalof the same, as the case may be. In so doing, one of the flaring ends(21, 28, or of the deflector is pushed in opposite the bore 15 of thepipestem, and the other flaring end (22, 29, or

is caused to face outward. The mouthpiece is next inserted, orre-inserted, so that its reduced portion 16 will close the recess llperipherally, while its neck portion 20 will be driven into theadjoining outwardly facing compartn'ient 22, 29 or 32, with the bore 17,running through said mouthpiece and the neck thereof, in directcommunication with said outwardly-facing compartment. The deflector isthen in its operative position.

Fig. l of the drawing shows that smoke cannot be drawn directly in astraight course from the bowl of the pipe through its stem andmouthpiece. A large portion of the draft will first be received andreflected backward by the compartment of the deflector which faces thebore in the stem. The other portion that flows past the saidcompartment, along the external downwardly-inclined grooves thereof,mostly serves to flll the central depression around the deflector, andonly part of it follows up the reversely-inclined external grooves ofthe compartment of the deflector, that is turned toward the mouthpiece,heal the outei end of the recess in the pipe-stem. The amount of thesmoke that reaches this end of the recess is then diverted backwardagain by the reduced stopper-portion and neck of the mouthpiece, andinto the latter-named compartment of the deflector finally some of thesmoke is reflected forward into and out of the bore of the mouthpiece.It is manifest that by causing it to follow this tortuous course, thesmoke drawn from the pipe is rid of its heavier constituents in transit,the same being deposited and settling upon or within the bulges orhollows of the deflector and its surroundings, so that none but thelighter tobacco-smoke can be inhaled at the mouthpiece.

Having described my invention, what I claim and desire to secure byLetters Patent is 1. A tobacco-pipe including a two-part smoke-deflectordivided by a central annular depression and having surface groovesreversely inclined therefrom.

A tobacco pipe including a smoke deflector made from a tri-lobed tubetwisted in the middle to divide it into two separate compartments havingreversely inclined surface grooves with an intervening centraldepression.

3. A tobacco pipe consisting of a bowl, a mo uthpiece therefor and arecessed stem connecting said bowl with said, mouthpiece, combined witha lobed deflector lodged in the recess of said stem, the lobes whereofextend longitudinally of the stem and adjoin ing mouthpiece, therebyaffording similarly ext-ending passages for the smoke between saidlobes.

Signed at the borough of Manhattan, in the county of New York and Stateof New York this 8th day of June A. D. 1909.
